reverse provides almost no power to the wheels in this Winnebago Chalet. I have added fluid to make sure that is not the problem. Forward gears are all strong.
Looking for simple solutions...
"I am guessing this indicates a rebuild?"
Not really. see www.transtar1.com You don't state the current mileage.
Your problem could be as simple as a stuck relay or valve. Usually the forward gears go first, not reverse. If you can't do the work yourself, since you can drive it, why not take it to a transmission shop familiar with Chev transmissions for a diagnosis? Tell them that you are not going to be buying a rebuilt transmission and want it fixed as cheaply as/if possible without a guarantee. If they do agree to help you, you will bear all responsibility if the unit fails in 1,000 miles. (or less) That's the chance you take. You did indicate that you want it cheap. Do you feel lucky?
